Summary
This case-control study examined blood levels of trace metals in amyotrophic lateral sclerosis (ALS).
The researchers found that selenium and zinc were inversely associated with ALS, particularly among patients with worse function, suggesting that supplementation with these nutrients may benefit such patients.
Further details can be found in the study.
